Infineon has announced the cost-optimised extension of its successful XC2000 automotive microcontroller portfolio. The new MCUs will give the medium-sized and compact car category access to the safety and convenience applications of the premium segment, whilst enabling their compliance with the strictest fuel consumption and pollutant emission requirements. Infineon says these new products will assist automotive system suppliers that want to broaden their offerings towards a wider performance range without introducing multiple microcontroller platforms.
Enabling 32-bit equivalent performance at 8-bit costs the new 16-bit devices address low-end and ultra-low-cost automotive applications and support cost reductions of existing body (with XC2200 series), safety (with XC2300 series) and powertrain (with XC2700 series) designs. Typical applications addressed by the new XC2000 16-bit devices include low-cost body control modules (BCM), low-cost airbags or low-end engine management designs. To further optimise the PCB size Infineon offers its new XC2000 devices in tiny cost-optimised packages.
The new 16-bit low-cost devices in the XC2000 family are based on a high-performance C166SV2 CPU with 5-stage pipeline. The products offer a Multiply Accumulate (MAC) unit with DSP functionality for dedicated filter algorithms. They also provide an optimised peripheral set for low-cost applications with up to two CAN nodes, up to four flexible serial interfaces and up to 19 ADC channels. The high-speed 12-bit ADCs provide a fast conversion time of less than 1µs. An integrated window watch dog with independent clock reduces the demand of external components for automotive applications. On-chip power supply, power control and debug support enable an easy design.
The new low-cost devices are offered with flash capacities of 32KB, 64KB, 96KB and 160KB, which expands the scalability of the whole XC2000 family from 32KB to 1.6MB flash memory. An optimised PIN-out results in an increased number of available I/Os with up to 49 I/Os within a 64-pin package. Infineon offers derivates in cost optimised packages like VQFN-48 with small dimensions of 7 x 7mm for footprint critical applications.
